-* pemalloc
-* unions
-* callbacks and function pointers
-* let impl_Var point to impl_arg, just like decl_var?
\ No newline at end of file
+* think about a better system for EXTVARs, separate \set and \get functions are clunky
+* fix right recursion of let_exp and set_exp
+* improve varargs support, currently it's impossible to map e.g. curl_easy_setopt
+* impl_var.name: remove leading '$'
+* really solve the array/pointer problem
+
+* variadic macros
+* predefined macros
+ * __COUNTER__ counter starting from 0, incremented each time expanded
+ * __BASE_FILE__ current PSI file
+ * __INCLUDE_LEVEL__ include level
+ * __TIMESTAMP__ lmod of current source file
+* builtins
+* int128
+* very small real numbers
+* cache tokens of files and copy tokens if used for further processing
+
+* optimized inlines like htonl
